In the detailed description that follows, many specific details are presented in order to provide a comprehensive understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be implemented without the need for some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present invention by illustrating examples of the present invention. In the accompanying drawings and the following description, at least some of the well-known structures and technologies are not shown in order to avoid unnecessary ambiguity in the present invention; and, for clarity, the sizes of some structures may be exaggerated. In addition, the features, structures, or characteristics described below may be combined in any suitable manner in one or more embodiments.
[0038] The directional terms used in the following description refer to the directions shown in the figures and do not limit the specific structure of the braking device and vehicle of this utility model. It should also be noted that, in the description of this utility model, unless otherwise specified or limited, the terms "installation" and "connection" should be understood broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; and can be directly or indirectly connected. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.
[0039] In order to better understand the present invention, Figures 1 to 9 The braking device and the vehicle according to the embodiment of the present utility model are described in detail.
[0040] See also Figures 1 to 4According to an embodiment of the present invention, a braking device 100 is proposed, including a base 10, a braking member 20, a driving assembly, a locking member 50 and a reset assembly 60. The braking member 20 includes a main body 21 and a clamping portion 22 provided on the main body 21. The main body 21 is rotatably connected to the base 10; the driving assembly includes a driving assembly 30 and a moving assembly 40. The moving assembly 40 has a degree of freedom of movement relative to the braking member 20 along a first direction X. The driving assembly 30 is connected to the moving assembly 40 and drives the moving assembly 40 to move along the first direction X toward the side where the clamping portion 22 is located, so that The main body 21 and the clamping portion 22 rotate to a locked position relative to the base 10, and the clamping portion 22 clamps the brake component to be locked; the locking member 50 abuts against at least a portion of the moving component 40, and the locking member 50 can prevent the moving component 40 from moving away from the clamping portion 22, so that the main body 21 and the clamping portion 22 remain in a locked position relative to the base 10; the reset component 60 is connected to at least one of the brake component 20 and the moving component 40, and the reset component 60 drives the main body 21 and the clamping portion 22 to rotate to an unlocked position relative to the base 10, so that the clamping portion 22 is separated from the component to be locked.
[0041] Optionally, the base 10 may be a supporting bottom plate structure, and the brake member 20 , the drive assembly, and the locking member 50 in this embodiment may all be disposed on the base 10 .
[0042] The brake member 20 serves as the braking body of the braking device 100. Optionally, the brake member 20 specifically includes a main body 21 and a clamping portion 22. The main body 21 is the base portion of the brake member 20. The clamping portion 22 can be a hook-shaped structure, so that it can be clamped with the component to be locked. For example, the component to be locked can be a ratchet with teeth, and the braking of the ratchet is achieved by clamping the clamping portion 22 with the teeth.
[0043] In this embodiment, the driving force is specifically provided to the entire structure by the driving assembly 30. The driving assembly 30 can drive the moving assembly 40 to move in the first direction X. Optionally, the first direction X is a pre-set desired direction. When the moving assembly 40 moves on the base 10, it can further drive the brake member 20 to rotate on the base 10, so that the clamping portion 22 of the brake member 20 gradually approaches the part to be locked until the clamping portion 22 is completely engaged with the part to be locked to stop it from moving.
[0044] After completing the above braking, if Figure 3 As shown, at this time, the locking member 50 forms an abutment with the moving component 40, and the locking member 50 can prevent the moving component 40 from moving in the reverse direction in the first direction X, ensuring that the moving component 40 and the braking member 20 remain stationary after braking, thereby ensuring the braking stability of the locked component and avoiding the moving component 40 from moving back to cause the braking to fail.
[0045] When the brake needs to be released, the driving assembly 30 provides a reverse moving force to the moving assembly 40, causing it to move in the reverse direction in the first direction X, thereby driving the clamping portion 22 of the brake member 20 to gradually move away from the part to be locked until the two are separated and no longer in contact, completing the process of releasing the brake. Figure 2 shown.
[0046] It should be noted that at this time, the driving force provided by the driving component 30 to the moving component 40 needs to overcome the resistance caused by the locking component 50 to the moving component 40, that is, to complete the unlocking of the locking component 50, so that the moving component 40 can move normally in the reverse direction in the first direction X and return to the position before braking, thereby completing the overall brake unlocking.
[0047] It can be seen from this that the user only needs to control the driving direction of the driving component 30 according to the actual braking needs to complete the braking or unlocking of the locked component, and the driving component 30 provides the dominant force for the entire braking process.
[0048] The present invention provides a braking device 100 in which a driving assembly 30 drives a moving assembly 40 to move in a first direction X and further drives a braking member 20 to rotate relative to a base 10, so that a locking portion 22 in the braking member 20 engages with a component to be locked, thereby braking the component to be locked. In this embodiment, the abutment between the locking member 50 and the moving assembly 40 achieves a locking function after braking, preventing the structure from failing due to the movement of the moving assembly 40 after braking, reducing the possibility of brake failure and providing better structural stability for the braking device 100 as a whole after braking, providing a reliable guarantee for sustainable braking. Furthermore, the braking device 100 in this embodiment has a simple structure and a more simplified structure than current pneumatic or hydraulic brakes, reducing structural complexity. Compared with traditional pneumatic brake systems, the braking device 100 in this embodiment has advantages such as fast response, flexible control, compact structure, and environmental friendliness. Compared with traditional hydraulic brake systems, the braking device 100 in this embodiment eliminates a series of hydraulic components, further simplifying the related structure and thus further reducing the curb weight of the vehicle. At the same time, it also overcomes the shortcomings of traditional hydraulic brake systems such as long brake lines and easy leakage of brake fluid, which helps save equipment space.
[0049] As an alternative embodiment, see Figure 4 and combined Figure 5 The moving component 40 includes a moving base 41 and a locking protrusion 42 arranged on the moving base 41. The locking protrusion 42 protrudes out of the moving base 41 and is enclosed with the moving base 41 to form a card slot 44. The locking member 50 can be at least partially located in the card slot 44 and be engaged with the locking protrusion 42 along the first direction X.
[0050] In this embodiment, a locking protrusion 42 is specifically provided in the moving component 40, and the locking protrusion 42 is used to complete the locking cooperation with the locking member 50. The locking protrusion 42 can form structural interference with the locking member 50 in the first direction X. After contact, the locking member 50 provides a blocking force to the locking protrusion 42.
[0051] Specifically, when the moving component 40 gradually moves to the left to drive the brake member 20 to gradually approach the part to be locked, since the locking member 50 always remains stationary on the base 10, the locking member 50 contacts the moving component 40 and moves relative to each other until the locking member 50 passes over the locking protrusion 42 therein and abuts against the card slot 44. Even if the driving component 30 no longer provides driving force, the moving component 40 at this time cannot move back under the card action of the locking member 50. The locking member 50 provides a blocking force to the moving component 40 at the position of the card slot 44, completing the locking of the moving component 40, and then realizing the braking lock of the brake member 20.
[0052] An embodiment of the present utility model provides a braking device 100, which can better provide a blocking force for the reverse movement of the moving component 40 by arranging a locking protrusion 42 on the moving base 41 to cooperate with the locking member 50. With the help of the structural interference between the locking protrusion 42 and the locking member 50, the locking process is more stable and reliable, providing a guarantee for stable locking.
[0053] As an alternative embodiment, see Figure 5 The locking protrusion 42 includes a first slope surface 42a and a second slope surface 42b arranged successively in the first direction X. The extension length of the first slope surface 42a in the first direction X is greater than the extension length of the second slope surface 42b. The slope formed between the first slope surface 42a and the surface of the mobile base 41 where it is located is smaller than the slope formed between the second slope surface 42b and the surface of the mobile base 41 where it is located. The locking member 50 blocks the movement of the moving component 40 by abutting against the second slope surface 42b.
[0054] In this embodiment, the specific structure of the locking protrusion 42 is designed, that is, the slopes of the first slope 42a and the second slope 42b are designed to be differentiated. Specifically, the slope of the first slope 42a is smaller than the slope of the second slope 42b. The first slope 42a is gentler and the second slope 42b is steeper.
[0055] Since the second slope 42b has a larger slope, after braking is completed, the locking member 50 can abut against the second slope 42b. The steeper second slope 42b can form a sufficient barrier to the locking member 50, thereby improving the stability after braking and reducing the risk of the moving component 40 moving back.
[0056] When the brake needs to be released, the driving assembly 30 drives the moving assembly 40 to move to the right to overcome the resistance provided by the locking member 50. The locking member 50 needs to cross the steeper second slope 42b and then enter the gentler first slope 42a, thereby releasing the brake; when the brake needs to be continued, the driving assembly 30 drives the moving assembly 40 to move to the left, and the locking member 50 can enter the steeper second slope 42a from the gentler first slope 42a. The first slope 42a will not generate a large resistance with the locking member 50 to complete the braking process. After the braking is completed, the locking member 50 crosses the first slope 42a and abuts against the second slope 42b, thereby achieving brake locking.
[0057] An embodiment of the present invention provides a braking device 100, which provides a first slope surface 42a and a second slope surface 42b with different slopes, so that the second slope surface 42b forms a sufficient blocking force on the locking member 50 while the first slope surface 42a does not block the braking process. This improves the stability after braking and ensures the operational convenience of the braking process.
[0058] As an alternative embodiment, see Figure 4 and combined Figure 5 The moving component 40 also includes a limiting protrusion 43 provided on the moving base 41. The limiting protrusion 43 is located on the side of the locking protrusion 42 away from the card slot 44 in the first direction X. The surface of the limiting protrusion 43 close to the locking protrusion 42 is enclosed with the locking protrusion 42 to form an accommodating recess 45. The locking piece 50 can abut against the accommodating recess 45 and limit the movement of the moving component 40 by abutting against the limiting protrusion 43.
[0059] In this embodiment, a limiting protrusion 43 is further provided on the movable base 41 , and together with the locking protrusion 42 , forms an accommodating recess 45 . The locking member 50 is located in the accommodating recess 45 after being unlocked.
[0060] The specific process is that when the moving component 40 moves to the left in the first direction X, the locking member 50 can overcome the resistance generated by the locking protrusion 42 and enter the card slot 44 to complete the locking process, until the clamping portion 22 of the brake member 20 is driven to rotate to the locking position; then in the process of releasing the brake, the moving component 40 moves to the right in the first direction X, and the locking member 50 gradually disengages from the card slot 44 and enters the above-mentioned accommodating recess 45 until the brake member 20 is separated from the part to be locked, thereby completing the unlocking process.
[0061] It can be seen from this that the purpose of setting the limiting protrusion 43 in this embodiment is to prevent the moving component 40 from moving further to the right, that is, after the locking member 50 completes the unlocking process in the accommodating recess 45, the locking member 50 will abut against the position of the limiting protrusion 43, thereby preventing the moving component 40 from continuing to move, and always restricting the locking member 50 in the accommodating recess 45 to avoid excessive disengagement of the moving component 40.
[0062] An embodiment of the present utility model provides a braking device 100, which provides a limiting protrusion 43 on a movable base 41, and utilizes this structure to form a blocking cooperation with a locking member 50, so that after the lock is released, the limiting protrusion 43 abuts against the locking member 50 and restricts it in the accommodating recess 45, thereby avoiding excessive movement of the movable component 40 and forming better structural protection for the movable component 40.
[0063] As an alternative embodiment, see Figure 4 and combined Figure 5 and Figure 6 The movable base 41 includes a first movable member 1, a second movable member 2 and a connecting member 3, one end of the connecting member 3 is connected to the first movable member 1 and the other end passes through the second movable member 2, the driving component 30 is movably connected to the first movable member 1 and the brake member 20 abuts against the second movable member 2, the locking protrusion 42 is provided on the first movable member 1, the driving component 30 can drive the first movable member 1, the connecting member 3 and the second movable member 2 to move in the first direction X in turn, and the second movable member 2 can drive the brake member 20 to rotate.
[0064] In this embodiment, the movable base 41 is set as a three-part structure, namely the first movable part 1, the second movable part 2 and the connecting part 3. The locking protrusion 42 is set on the surface of the first movable part 1 and forms a locking fit with the locking part 50. The second movable part 2 is used to form abutment with the brake part 20 and can drive the brake part 20 to rotate. The transmission between the two movable parts is completed through the connecting part 3.
[0065] Optionally, the first moving part 1 and the second moving part 2 can be block structures, and the connecting part 3 can be a rod-shaped structure. One end of the connecting part 3 is connected to the first moving part 1, and the other end must pass through the second moving part 2 and complete the fixation. This application does not make any special restrictions on the specific structure in the moving base 41, as long as it meets the movement requirements.
[0066] Optionally, the connecting end of the connecting member 3 and the first movable member 1 can be fixed by a pin and a retaining spring, and the connecting end thereof with the second movable member 2 can be tightened with a push head by a screw after passing through the second movable member 2 to complete the connection. This application does not specifically limit the specific connection method.
[0067] The embodiment of the present invention provides a braking device 100 , which divides the movable base 41 into three parts, thereby providing a feasible movable structure, and utilizes a transmission method to drive the rotation of the braking member 20 and form a stable locking fit.
[0068] As an alternative embodiment, see Figure 4 The movable base 41 further includes a telescopic member 4 , which is sleeved on a portion of the connecting member 3 and abuts between the first movable member 1 and the second movable member 2 .
[0069] Optionally, the telescopic member 4 may be a spring structure, and the telescopic member 4 is sleeved on the connecting member 3 , so that a telescopic force can be generated between the first moving member 1 and the second moving member 2 .
[0070] Specifically, when the movable base 41 moves to the left, the first movable member 1 moves first, causing the distance between the first movable member 1 and the second movable member 2 to gradually decrease. Under the action of the connecting member 3, the second movable member 2 is driven to move to the left. The middle telescopic member 4 is squeezed by the movable members on both sides to form a compressed state, and finally drives the rotation of the brake member 20 to complete the braking process.
[0071] When the movable base 41 moves to the right, it will first drive the first movable member 1 to move to the right. At this time, the telescopic member 4 is gradually released and forms a reverse rebound force on the first movable member 1, so that the first movable member 1 can be smoothly reset to the right, thereby enabling the first movable member 1 to overcome the contact resistance of the locking member 50 and return to the initial position.
[0072] An embodiment of the present utility model provides a braking device 100, which arranges a telescopic member 4 on the connecting member 3 and utilizes the telescopic performance of the telescopic member 4 to drive the reset of the first movable member 1, making it easier to realize the rotation recovery of the braking member 20, and easier to complete the release of the brake of the entire structure, with a better unlocking effect.
[0073] As an alternative embodiment, see Figure 4 and combined Figure 6 The second movable member 2 includes a wedge block structure. In the direction gradually away from the first movable member 1 along the first direction X, the abutting surface between the second movable member 2 and the brake member 20 is inclined and gradually away from the brake member 20. The second movable member 2 presses down the brake member 20 through the abutting surface to make it rotate.
[0074] Optionally, in this embodiment, the second movable member 2 can be set as a wedge block structure, and the contact surface between the second movable member 2 and the brake member 20 is an inclined surface. This structure mainly drives the brake member 20 to rotate by pressing down.
[0075] When the second movable member 2 moves to the left in the first direction X, if the part to be locked is located on the lower side of the brake member 20 at this time, the inclined surface of the second movable member 2 abutting against the brake member 20 will gradually press down the brake member 20, causing it to rotate on the base 10 until the brake member 20 is pressed down and engaged with the part to be locked to complete the braking.
[0076] An embodiment of the present utility model provides a braking device 100, which converts the linear movement of the second movable member 2 into the rotation of the brake member 20 by setting the second movable member 2 as a wedge block structure and pressing down using the inclined surface of the second movable member 2 in contact with the brake member 20, thereby making it easier to achieve the engagement of the lower side component to be locked and completing the precise braking process.
[0077] As an optional embodiment, the brake member 20 abuts against the abutment surface via a rolling bearing, so that the brake member 20 is in rolling contact with the abutment surface.
[0078] Since the contact surfaces of the second movable member 2 and the brake member 20 will move relative to each other and form friction during the contact process, in order to reduce the wear of the contact surfaces between the two, a rolling bearing is provided between the two in this embodiment to form rolling contact between the two.
[0079] An embodiment of the present utility model provides a braking device 100, which arranges a rolling bearing between the second movable part 2 and the braking part 20, so that rolling friction is generated when relative displacement occurs between the two, thereby reducing the wear of the two structural surfaces during operation, increasing the service life of the product, and providing better safety protection for the structural parts.
[0080] As an alternative embodiment, see Figure 4 and combined Figure 7 The locking member 50 includes a receiving portion 51 and a protruding portion 52. The protruding portion 52 is arranged in the receiving portion 51 and protrudes from the receiving portion 51. The locking member 50 abuts against the moving component 40 through the protruding portion 52. The contact surface between the protruding portion 52 and the moving component 40 is an arc surface structure.
[0081] Optionally, the locking member 50 can be a set of spring steel ball lock pin subassemblies, in which the accommodating portion 51 can be a fixed seat structure, and the protruding portion 52 can be a spring steel ball lock pin. When the locking member 50 forms abutment with the moving component 40 to complete the locking process, the locking is completed after the protruding portion 52 abuts with the moving component 40, and the locking is completed after the protruding portion 52 is engaged with the locking protrusion 42.
[0082] Optionally, the protrusion 52 can be a spherical structure, so that the contact surface between the protrusion 52 and the moving component 40 is a curved surface structure, thereby making the contact surface between the two smoother. When the moving component 40 moves relative to the locking member 50, the curved surface structure can reduce the contact friction between the two, and at the same time, it can also better protect the structural parts and reduce the wear between the two.
[0083] An embodiment of the present invention provides a braking device 100, which utilizes a protrusion 52 to abut against the moving component 40 and sets the contact surface to an arc surface structure. While achieving locking of the braking component 20, it can also reduce the wear of the moving component 40 during movement, reduce the moving friction, and provide better safety protection for the structural parts.
[0084] As an alternative embodiment, see Figure 4 The braking device 100 also includes a reset assembly 60, which is connected to at least one of the braking member 20 and the moving assembly 40. The reset assembly 60 drives the main body 21 and the clamping portion 22 to rotate relative to the base 10 to an unlocked position to separate the clamping portion 22 from the component to be locked.
[0085] In this embodiment, it is mainly considered that after the moving component 40 drives the brake component 20 to complete braking, due to the locking effect of the locking component 50, it is necessary to use the reset component 60 to drive the brake component 20 to complete the brake unlocking. The reset component 60 can provide a restoring force to the brake component 20, and overcome the resistance of the locking component 50 through the restoring force, so that the brake component 20 can return to the initial position to complete the unlocking process.
[0086] The present application does not impose any particular restrictions on the specific type of reset assembly 60 or the restoring force it provides. It only needs to be able to drive the brake member 20 to overcome the locking resistance and complete the reset. Therefore, when the brake member 20 needs to be unlocked, the driving assembly 30 still provides the primary driving force. Simultaneously, the reset assembly 60 can provide auxiliary force to the brake member 20, gradually separating it from the locked component until the brake member 20 is separated from the locked component.
[0087] An embodiment of the present utility model provides a braking device 100, which provides a restoring force to the brake member 20 by setting a reset component 60. The reset component 60 can be used to further help the brake member 20 leave the part to be locked to complete the unlocking process, thereby improving the brake unlocking ability and facilitating the brake member 20 to return to its initial position.
[0088] As an alternative embodiment, see Figure 4The reset assembly 60 includes a torsion member 61 and a positioning shaft 62. The positioning shaft 62 passes through the brake member 20 and the torsion member 61 is sleeved on the positioning shaft 62. The moving assembly 40 can drive the brake member 20 to rotate around the positioning shaft 62. The torsion member 61 is configured to provide a torsional force to the brake member 20 away from the part to be locked.
[0089] Optionally, the torsion member 61 can be a torsion spring structure. When the moving assembly 40 gradually moves to the left to complete braking, the torsion member 61 twists and generates a clockwise torsional force. The driving force generated by the driving assembly 30 needs to overcome the above torsional force, so that the brake member 20 continues to rotate until it engages with the part to be locked and the locking member 50 completes locking.
[0090] When the brake is unlocked, the drive assembly 30 provides a reverse driving force to move the moving assembly 40 to the right. At the same time, the clockwise torsional force formed by the torsional member 61 is released, further driving the brake member 20 to rotate clockwise so that it gradually moves away from the part to be locked until the unlocking process is completed.
[0091] That is to say, during the unlocking process, the drive assembly 30 always provides the main driving force to drive the brake member 20 away from the part to be locked. At the same time, the torsion member 61 can provide auxiliary torsion force to the brake member 20 to synchronously drive the brake member 20 to release the brake.
[0092] An embodiment of the present invention provides a braking device 100, which facilitates unlocking and resetting the brake member 20 by setting the reset component 60 as a torsion member 61 and utilizing the torsion force generated by the torsion member 61 to release the brake. This provides a guarantee for the subsequent unlocking function.
[0093] As an alternative embodiment, see Figure 4 The reset assembly 60 includes a first extension portion 63 and a second extension portion 64. The first extension portion 63 protrudes from the main body portion 21 toward the moving assembly 40, and the second extension portion 64 protrudes from the moving assembly 40 toward the brake member 20. The second extension portion 64 can drive the first extension portion 63 to move in the first direction X to drive the brake member 20 to leave the part to be locked.
[0094] In this embodiment, the reset component 60 is configured as a structure of a first extension portion 63 and a second extension portion 64, wherein the first extension portion 63 is protrudingly provided on the main body portion 21 and the second extension portion 64 is protrudingly provided on the moving component 40, and the first extension portion 63 and the second extension portion 64 can form structural contact.
[0095] The reset assembly 60 specifically plays a role in the unlocking process. When the brake of the brake member 20 needs to be released, the driving assembly 30 drives the moving assembly 40 to move to the right. Since the second extension portion 64 protrudes toward the brake member 20 and can form contact with the first extension portion 63, during the movement of the moving assembly 40, the contact between the second extension portion 64 and the first extension portion 63 drives the rotation of the brake member 20, thereby also providing a driving force for the rotation of the brake member 20.
[0096] When the first extension portion 63 and the second extension portion 64 come into contact, the moving component 40 can provide a driving force in the first direction X to the brake member 20, so that the brake member 20 can rotate. The driving force at this time needs to overcome the resistance generated by the locking member 50, so that the moving component 40 can be unlocked and moved, and finally drive the brake member 20 to leave the part to be locked.
[0097] An embodiment of the present utility model provides a braking device 100, which provides another structural form of the reset component 60. Through the structural abutment of the first extension part 63 and the second extension part 64, the moving component 40 directly drives the brake part 20 to rotate, thereby achieving an unlocked state, providing a second driving force for resetting the brake part 20, and further ensuring the unlocking ability of the brake part 20.
[0098] As an alternative embodiment, see Figure 8 The driving component 30 includes a driving member 31 and a swinging member 32. The driving member 31 is connected to one end of the swinging member 32 and can drive the swinging member 32 to swing within a predetermined angle range. The other end of the swinging member 32 is connected to the moving component 40 and can drive the moving component 40 to move in the first direction X.
[0099] Optionally, the specific structure of the driving component 30 is to connect the swinging member 32 through the driving member 31 and drive the swinging member 32 to swing at a predetermined angle. It can be understood that the swinging member 32 needs to swing back and forth within the predetermined angle range to realize the reciprocating movement of the moving component 40. As for the predetermined angle, it needs to be calculated and determined according to actual needs.
[0100] When the swinging member 32 swings, it can drive the moving assembly 40 connected to the other end to move in the first direction X, that is, the circumferential swing of the swinging member 32 is converted into a linear movement of the moving assembly 40, thereby further driving the rotation of the brake member 20. The reciprocating swing of the swinging member 32 corresponds to the reciprocating movement of the moving assembly 40. Optionally, the driving member 31 can be a motor and the swinging member 32 can be a rod-shaped structure.
[0101] An embodiment of the present utility model provides a braking device 100, which provides a driving method for a driving component 30, and realizes circumferential swing through the connection between the driving member 31 and the swing member 32, thereby converting the circumferential swing into a linear movement of the moving component 40, providing a stable driving force for the braking and unlocking process.
[0102] As an alternative embodiment, see Figure 2 and Figure 3 A guide groove 11 extending along the first direction X is provided on the base 10, and the moving component 40 includes a guide protrusion 46 protruding toward the base 10. The guide protrusion 46 is inserted into the guide groove 11 and can move along the first direction X in the guide groove 11.
[0103] In order to ensure that the moving component 40 can move stably along the first direction X on the base 10, a guide groove 11 extending along the first direction X is provided on the base 10 in this embodiment. The guide protrusion 46 provided on the moving component 40 is inserted into the guide groove 11, which can form a connection while also providing guidance for the movement of the moving component 40.
[0104] An embodiment of the present utility model provides a braking device 100, which uses the guide groove 11 and the guide protrusion 46 to form a plug-in fit to provide stable guidance for the moving component 40 in the first direction X, thereby preventing the moving component 40 from deviating during the movement process, thereby causing braking instability. At the same time, the plug-in connection method is conducive to the detachability of the moving component 40 and the base 10, thereby facilitating the installation of the device.
[0105] As an alternative embodiment, see Figure 4 and Figure 5 A waist-shaped hole 47 is provided on the moving component 40. One end of the swinging member 32 is connected to the driving member 31, and the other end is inserted into the waist-shaped hole 47 and can move in the waist-shaped hole 47. The extension direction of the waist-shaped hole 47 intersects with the first direction X. When the swinging member 32 swings, the end portion moves in the waist-shaped hole 47 to drive the moving component 40 to move in the first direction X.
[0106] In order to convert the arc-shaped swing of the swing member 32 into a linear movement of the moving component 40 in the first direction X, a waist-shaped hole 47 is provided on the moving component 40 in this embodiment, and the extension direction of the waist-shaped hole 47 is set to intersect with the first direction X, so that the plug-in end of the swing member 32 and the waist-shaped hole 47 can move in the waist-shaped hole 47, thereby realizing the linear movement of the moving component 40 in the first direction X.
[0107] At this time, the waist-shaped hole 47 needs to overlap with the guide groove 11 on the base 10. The end of the swinging member 32 moves back and forth in the waist-shaped hole 47, driving the moving component 40 to move back and forth on the guide groove 11, thereby driving the brake member 20 to achieve braking or unlocking.
[0108] Optionally, the end of the swing member 32 can be inserted into the waist-shaped hole 47 using a pin and fixed by a spring structure, so that the end of the swing member 32 can be movably connected in the waist-shaped hole 47 and has a certain degree of freedom of movement.
[0109] An embodiment of the present utility model provides a braking device 100, which converts the swinging of the swinging member 32 into the movement of the moving member 40 in the first direction X by setting a waist-shaped hole 47 on the moving member 40 and cooperating with the guide groove 11 on the base 10, thereby providing further guarantee for the precise movement of the moving member 40 in the first direction X, thereby improving the reliability and stability of the braking of the driving brake member 20.
[0110] As an alternative embodiment, see Figure 8 The driving assembly 30 further includes a support member 33 , which is disposed on the base 10 . One end of the swing member 32 is connected to the driving member 31 and partially abuts against the support member 33 to limit the movement of the swing member 32 .
[0111] Optionally, the support member 33 can be a block structure, which is arranged on the base 10 to support the swing member 32, that is, the swing member 32 is clamped between the support member 33 and the driving member 31, and the support member 33 can play a certain limiting role on the swing member 32.
[0112] The driving member 31 mainly drives the swinging member 32 to swing. Due to the supporting effect of the support member 33 at the bottom of the swinging member 32, the swinging member 32 reduces its up and down movement, thereby stably clamping the swinging member 32 between the driving member 31 and the support member 33, and only exerting its swinging effect. Optionally, the support member 33 and the swinging member 32 can be connected by a flange cap, which can reduce the wear in the swinging circumferential direction. This application is not limited to this.
[0113] An embodiment of the present invention provides a braking device 100, in which a support member 33 is provided at the bottom of the swing member 32, and the swing member 32 is fixed by clamping it together with the driving member 31, thereby preventing the swing member 32 from moving up and down while swinging, and improving the stability of driving the moving component 40.
[0114] As an alternative embodiment, see Figure 2 and Figure 3The braking device 100 further includes a limit member 70 , which is disposed on the base 10 and located on one side of the moving component 40 in the first direction X. The limit member 70 is configured to limit the movement of the moving component 40 .
[0115] Optionally, a limit member 70 can be further provided on the base 10. The limit member 70 can be a block structure, which is set on the travel route of the moving component 40 in the first direction X, so as to form a structural barrier to the moving component 40 and limit the movement range of the moving component 40 in the first direction X.
[0116] This is mainly due to the consideration of excessive movement of the moving component 40 during the braking process. Specifically, a limit member 70 can be set at the end of the travel of the guide groove 11. When the moving component 40 moves excessively, it will be blocked by the limit member 70, thereby preventing the moving component 40 from detaching and protecting the effectiveness of the braking.
[0117] An embodiment of the present utility model provides a braking device 100, which provides a reliable moving range for the moving component 40 by arranging a limit member 70 on the base 10 to block the movement of the moving component 40, thereby forming a limit protection for the moving component 40 and providing a guarantee for a stable and reliable braking process.
[0118] As an alternative embodiment, see Figure 1 The braking device 100 further includes a protective member 80 , which is connected to the base 10 and covers the driving assembly, the braking member 20 and the locking member 50 .
[0119] Optionally, the protective member 80 can be a plate-like structure, such as a sheet metal cover. After completing the connection of the above-mentioned components, the protective member 80 can be covered and connected to the base 10, thereby forming isolation protection for the drive assembly, the brake member 20 and the locking member 50, preventing the influence of impurities in the external environment on the components, and at the same time preventing the movement and tilting caused by uneven force in the vertical direction during braking. The protective member 80 can be detachably connected to the base 10 by bolts.
[0120] The embodiment of the present invention provides a braking device 100 , which improves the sealing of internal braking components by connecting a protective member 80 to a base 10 , thereby providing effective protection for the precise fit between components.
[0121] According to an embodiment of the present invention, a vehicle is provided, comprising a rotating assembly 200 and the braking device 100 as described above, such as Figure 1 and Figure 9As shown, the rotating assembly 200 includes a driving motor 201 and a rotating wheel 202 . The driving motor 201 is connected to the rotating wheel 202 and can drive the rotating wheel 202 to rotate. The braking device 100 is clamped to the rotating wheel 202 through the clamping portion 22 to brake the rotating wheel 202 .
[0122] Normally, the driving motor 201 needs to be connected to the rotating wheel 202 to drive the rotation of the rotating wheel 202. Optionally, the rotating wheel 202 can be a ratchet structure. The rotating wheel 202 is installed on the output shaft of the driving motor 201 through an axis connecting member 3 with a matching spline structure in the middle. The circumferential positioning is achieved by the spline structure and the key, and it is fixed by two Kimi screws to prevent it from moving up and down in the axial direction.
[0123] When braking the rotating wheel 202 , the brake member 20 engages the rotating wheel 202 via the engaging portion 22 , for example, engaging the engaging portion 22 in the tooth groove of the ratchet, so that the rotating wheel 202 stops rotating to complete the braking process.
[0124] Optionally, the vehicle may also experience a "false" parking situation. Specifically, if the vehicle is parked on a slope, the swinging member 32 rotates clockwise to move the moving assembly 40 to the left and drive the clamping portion 22 of the brake member 20 to clamp with the rotating wheel 202. However, if the clamping portion 22 presses against the rectangular tooth top of the rotating wheel 202, the moving assembly 40 cannot continue to move to the left. When the vehicle slides down the slope and causes the rotating wheel 202 to rotate a certain angle, the clamping portion 22 will be forced to automatically clamp into the rectangular tooth groove of the rotating wheel 202, and the "false" parking situation will be converted into a successful parking situation.
[0125] The effectiveness of vehicle braking can be verified through calculations. The specific process is as follows:
[0126] When the output torque of the driving motor 201 is T0, the effective radius of the rotating wheel 202 is R0, the sliding friction coefficient between the clamping portion 22 and the rotating wheel 202 is μ0, and the safety factor is A, the pull-out force F0 required for the clamping portion 22 to release the brake can be calculated.
[0127] F0=μ0×A×T0 / R0;
[0128] The distance between the rotation axis of the conventionally designed brake member 20 and the front end centerline of the clamping portion 22 during rotation is L0. Therefore, it can be concluded that the torque T1 of the torsion member 61 required by the clamping portion 22 is at least:
[0129] T1=F0×L0;
[0130] If the spring constant of the torsion member 61 is selected as B, it can be obtained that the angle θ1 rotated by the torsion member 61 from releasing the brake to braking is:
[0131] θ1=T1 / B;
[0132] If the vertical distance between the rotation axis of the brake member 20 and the normal of the contact point between the second moving member 2 of the wedge-shaped block structure and the rolling bearing during braking is L1, the angle of the inclined surface of the second moving member 2 is θ0 and its own mass is G, the vertical force F1 exerted on the inclined surface of the second moving member 2 during braking is:
[0133] F1=T1 / L1;
[0134] And the thrust F2 that the second moving member 2 needs to overcome in the first direction X is:
[0135] F2=F1cosθ0+G;
[0136] After obtaining the above data, the following relationship must be satisfied to ensure normal function use:
[0137] F2D≤Δx1C;
[0138] D(Δx1C-Δx0)≥(Δx2)C;
[0139] Among them, Δx0 is the increased compression of the telescopic part 4 from releasing the brake to braking, C is the spring constant of the telescopic part 4, D is the selected safety factor, Δx1 is the compression of the telescopic part 4 when braking is successful, and Δx2 is the compression of the telescopic part 4 when the brake is released.
[0140] The present invention provides a braking device and a vehicle. A driving assembly drives a movable assembly to move in a first direction, further driving a braking member to rotate relative to a base, so that a locking portion in the braking member engages with a component to be locked, thereby braking the component to be locked. In this embodiment, the abutment between the locking member and the movable assembly achieves a locking function after braking. This prevents braking failure caused by the movement of the movable assembly after braking, reduces the possibility of braking failure, and provides improved structural stability for the braking device as a whole after braking, providing a reliable guarantee for sustainable braking. Furthermore, the braking device in this embodiment has a simple structure and a more simplified structure than existing pneumatic or hydraulic brakes, reducing structural complexity. Compared to traditional pneumatic brake systems, the braking device in this embodiment has advantages such as fast response, flexible control, compact structure, and environmental friendliness. Compared to traditional hydraulic brake systems, the braking device in this embodiment eliminates a series of hydraulic components, further simplifying the related structure and reducing the vehicle's curb weight. Furthermore, it overcomes the shortcomings of traditional hydraulic brake systems, such as long brake lines and easy leakage of brake fluid, thereby saving equipment space.
